' Application filed June 28 T all whom it may concern:

Be it known that I, WILLIAM AoK NsoN, a citizen of the United States, resid ng-at Pawtucket, in the county of Providence.

and State of Rhode Island, have invented new and useful Improvements in a Combined Doifer Guard and Oil-Nell Cover, of which the following is a specification.

This invention relates to certain new and useful improvements in a combined do-fier guard and oil well cover and the primary object of the invention is to provide a de vice which combines means to hold or latch the spindle of .a spinning machine in the bolster and which further serves to protect the oil well so as to prevent dust or other extraneous matter from entering the oil well.

A further object of the invention is to provide a device of this type inwhich open-- ing and closing of the oil well cover serves to effect movement of the latch out of and into spindle latching positions.

The invention further aims to providea device of this type which is economical and 5 simple in construction andwhich is positive and reliable in operation.

The invention has further and'other objects which will be later detailed and manifested in the course of the following descrlp- In the drawings 1- Figure l is a side elevation of the invention.

Figure 2 is a section on line 22 of Fig- Figure 3 is a fragmentary side elevation, parts being broken away and shown in section. 1

In proceeding in accordance with the present invention, the bolster casing is formed with a base 1 and an upwardly ex tending arm or upright 2, the latter formpart of said member engaging the inner end ing a post having an oil well or duct O, for

' supplying lubricant to the spindle'bearlng in the bolster base. The post is short and stocky and breakage thereof is consequently reduced to minimum. 7

y The spindle 3 has the usual whirl W which latter has its upper face disposed approximately in alinement with the upper end face of the post 2. The post is formed with an upwardly projecting housing 4 provided with a bearing in which a latching p1n 5 has horizontal sliding movement. The pin has an upper beveled face at its efiective end the pin.

The inner end ofthe pin is engaged by the part 11 and moved to latching position, while the move- ,ment'ofthe pin to unlatched position is efi'ected by engagement ofthe cam 8 with the inner. end groove 9.

10. In combination with a spindle and an oil ducttherefor, movable means to latch the spindle in position, means independent of the latching means to actuate the latter, and means to movably and independently mount the actuating means.
